Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative efforts belong to the protection scope of the present invention.

Referring to fig. 1-3, the present invention provides a technical solution:

the utility model provides an air volume adjusting valve, includes valve body 1, fixedly connected with fixed block 2 on the valve body 1, set up in the fixed block 2 with the communicating spout 3 of 1 interior pipeline of valve body, spout 3 department sliding connection has fan blade 4, around having sealing washer 5 on the outer wall of fan blade 4, under the effect of sealing washer 5, fan blade 4 can be better with the pipeline shutoff, be about to the valve close, rotate on the lateral wall of fan blade 4 and be connected with screw rod 6, screw rod 6 passes through threaded connection with fixed block 2. The screw rod 6 moves in the rotation, so that the position of the fan blade 4 in the pipeline is changed, the end part of the screw rod 6 is fixedly connected with a rotating handle 7, a disc 8 is fixedly connected onto the rotating handle 7, a scale rod 9 is fixedly connected onto the valve body 1, the air quantity in the pipeline at the moment can be obtained by looking over the scale on the scale rod 9 pointed by the disc 8, (when the pointed scale is zero, the valve is in a closed state, namely the fan blade 4 blocks the pipeline), and a limiting part for limiting the rotating handle 7 is arranged on the fixing block 2.

Specifically, as shown in fig. 1, the locating part includes side piece 10 of fixed connection on the lateral wall of fixed block 2, sliding connection has knee 11 on side piece 10, knee 11 is run through by screw rod 6, the cover is equipped with spring 13 on the knee 11, fixedly connected with fixture block 14 on the knee 11, draw-in groove 15 with fixture block 14 block is seted up to the bottom of disc 8, fixture block 14 can with draw-in groove 15 block, hand 7 receives the restriction and can't continue to rotate, prevent that the valve that the mistake touched and leads to from closing or opening.

Specifically, as shown in fig. 1, one end of the spring 13 is fixedly connected to the bending end of the bent rod 11, and the other end of the spring 13 is fixedly connected to the upper surface of the side block 10, so that the bent rod 11 can move upward under the action of the spring 13, and the clamping block 14 can be clamped with the clamping groove 15, thereby limiting the handle 7, and making the handle 7 unable to rotate at this time.

Specifically, as shown in fig. 1 and 3, end blocks 12 protrude from both ends of the bent rod 11, and an elastic rubber gasket is provided on a portion of the end block 12 that contacts the lower surface of the side block 10, so that the end block 12 can restrict the bent rod 11 and prevent the end of the bent rod 11 from separating from the side block 10, and the end block 12 is protected by the rubber gasket when moving upward to abut against the bottom of the side block 10, thereby preventing wear due to contact between the end block 12 and the side block 10.

In summary, when the valve provided by this embodiment needs to be closed, the curved rod 11 is pushed downwards, so that the fixture block 14 is separated from the clamping groove 15, the rotating handle 7 is rotated afterwards, and the screw rod 6 rotates along with the rotation, so that the fan blade 4 moves into the pipeline from the chute 3 until the outer wall of the fan blade 4 is attached to the inner wall of the pipeline, the pipeline at this time is blocked, the valve is closed, the curved rod 11 moves upwards under the action of the spring 13, so that the fixture block 14 can be clamped with the clamping groove 15, thereby limiting the rotating handle 7, so that the rotating handle 7 cannot rotate at this time, and the rotating handle 7 is effectively prevented from being mistakenly touched to rotate, and the valve is opened.

The previous description of the embodiments is provided to enable any person skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein may be applied to other embodiments without departing from the spirit or scope of the invention. Thus, the present invention is not intended to be limited to the embodiments shown herein but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
